Models are organized by outer diameter and wall thickness range — QX32 to QX89 suit small-diameter precision tubes (automotive, furniture, appliances), QX114 to QX325 cover mid-range structural and mechanical applications, and QX355 to QX711 are built for large-diameter, heavy-wall production such as oil & gas line pipe. The DFT series follows the same logic for square and rectangular profiles.
